Specificationof Letters Patent.

Application filed June 13, 1910. Serial No. 566,637.

To all whom'tt may concern:

Be it known that I, HENRI BESSONNET- FAVRE, a citizen of the Republic of France, residing at'Chatellerault, Vienne, France, have invented new and useful Improvements in Lifting-Chains with Multiple Concentric Spirals for Raising Liquids, which improvements are fully set forth in the following specification. Y

This invention relates to devices for raising water or other liquids, andmore particularly to such devices which comprise essentially a traveling chain or cable, and which are known as chain. pumps.

The object of the invention is to provide an improved construction of chain or cable which, while compact andsimple in construction, .will transport relatively large quantities ofliquid, and which will be ex- 20 tremely durable and little liable to get out of order.

To this end, I have devised a' cable which depends for its carrying power upon capil-' Y lary attraction or the natural adhesion of liquids. p

'My im-proved cable is constructed so as to contain a large number of intercommunieating spaces or interstices, in which spaces,

by virtue of its natural adhesive tendency, the liquid is held in suspension.

In order that my invention may be readily understood, reference is had to the accompanying drawings, forming a part of thisspecification, and in which,

showing my improved conveyer in use, parts being in section; Fig. 2 is; a fragmentary elevation, on an enlarged scale, showing the construction of the conveyer, and, Fig. 3 is 40 asimilar view, parts of the con'veyerbeing shown in section.

Referring to Figs. 2 and 3, my improved conveyer consists essentially of a plurality of concentrically arranged open work tubular elements, here illustrated as helical springs. Two of such springs, designated B and O, respectively,are shown, the inner one B, being shown as formed of' smaller wire than the outer one, and having its convolutions closer together. To form a support for these springs or coils, I provide a centrally arranged chain or cable Awhich,

as shown, consists of links of 8-shape, extendlng throughout the length of the con- Figure l is a side elevation of a pump- In order to prevent undue stretching of the wire coils B and C under the weight of the water, as well as to hold these coils properly spaced in the position illustrated in the Patented Apr. 4, 1911.

drawing, they are secured at intervals to the cham A by passing one or more times through a link of the chain, as illustrated at B and C in Fig. 2.

The complete endless conveyer or cable,

constructed as described, is adapted to be I mounted upon a grooved pulley P, over a well, so that the lower portion of the conveyer is immersed in the water, as shown in Fig. 1.. A weighted pulley P may be hung in the bottom of the cable so as to preserve a proper tension, if desired.

- The size of the wire of the several coils, the distances apart of these coils, and of the consecutive turns of each coil, is governed by the particular use to which the conveyer is to be put. The viscosity of the liquid to be pumped and the speed at which the cable is to be run, are factors in determining the relative spacing and size of the coils, as it is obvious that, where the liquid is viscous,

the interstices may be larger than in the case of a very limpid liquid. Also, it is obvious that any number of coils desired may be employed, depending upon the capacity required, the greater the number of coils, the greater the amount of liquid lifted.

Whatever the specific arrangement adopted, it will be observed that between the concentric tubular coils and between the innermost coil and the chain, annular spacesare formed, and that these spaces arerendered intercommunicating by virtue of the spaces between the adjacent turns of each 0011.

When the conveyer is submerged, the liquid fills all of these spaces and interstices, and as the conveyer travels upward the liquid is held in suspension in suchinterstices, the spacing of the coils being so designed that, for 'the particular liquid being conveyed,

capilliary or'natural adhesion is sufficient to cause the liquid to remain in the conveyer.

When the liquid laden cable reaches the pulley P and passes over the same, the liquid will be thrown from the cable by centrifugal force in the direction of a tangent to the pulley P, and will strike the shield or cover placed over such pulley, and be deflected into a discharge spout.

To produce the most eflicient operation of the device it should be run at a speed that will insure the total disengagement of the liquid from the cable, in the manner just described.

It will thus be seen that I have provided a simple and efiicient pump or liquid conveyer which may be formed wholly of metal or other durable or non-absorbent material, and it is thought that the advantages of my improved construction will be evident to those skilled in such matters.

What I claim is 1. Ina chain pump, a conveyor comprising a plurality of openwork tubular elements concentrically arranged and separated so as to provide between themselves an annular space adapted to contain the liquid to be conveyed.

2. In a chainpump, a conveyor compris ing a plurality of helical springs concentrically arranged and separated so as to provide between themselves an annular space 1 adapted to contain theliquid to be conveyed. 3. In a chain pump, a conveyer compriseeaao ing a plurality of helical springs concentrically arranged and separatedso as to provide between themselves an annular space adapted to contain the liquid to be conveyed, and a centrally disposed inextensible ing an endless cable formed of impervious non-absorbent material, said cable having within itself intercommunicating spaces or interstices adapted to hold in suspension therein the liquid to be conveyed.

5. In a chain pump, a conveyer comprising an endless cable made up of a plurality of structural elements formed of non-absorbent material, said elements being so arranged as to provide between themselves intercommunicating spaces of a size adapted to hold in suspension, by virtue of natural adhesion, the liquid to be conveyed, 1

In testimony whereof I have signed this specification in the presence of two subscrib- 111g witnesses.
